The official Burger King Twitter account was hacked on Monday morning, forcing the chain to take it down before returning to the social network later in the day.

Whoever was behind the hack must have preferred McDonald's, since they switched out the Burger King logo with a McDonald's imprint. The Burger King Twitter account was taken offline at about 1:15 p.m. ET, but not before the hackers were posting for about two hours, with posts that became more and more graphic and explicit.

Bryson Thorton, Burger King's director of global communications and culture, said, "We apologize to our fans and followers who have been receiving erroneous tweets about other members of our industry and additional inappropriate topics."

Many believe that hacking group Anonymous was behind the attack, but they later denied that was the case.
